An idea worth spreading

I have spent most of the past twenty-five years studying human odors, and this has got me thinking about their role in modern civilization. We each have our own individual natural body odors, which are recognizable and are supposed to convey messages to those surrounding us. Over the past four thousand years we have tinkered with our own natural body smell. The first was perfumes, which are made from flowers, which are part of the sex organs of plants. To these we often add just a bit of musk, which is the sexual odor musk deer, which attracts other deer (and, presumably us as well). In the 1880s antiperspirant was invented, which shuts off most of our natural odors. We also bathe frequently. Today we leave the house with the artificial odors of a variety of cosmetic and cleaning products, covering up our natural odor, and probably attracting people who are not our genetic smell-mates.

My TED story

Attended the amazing TEDx in Jaffa and provided background music for the TEDx youth at Rogozin Bialik School in Tel Aviv. Have my own mini-blog on TED where I talk about how various talks intertwine with my life experiences. Hope to co-organize a TEDx during the next couple of years. TED continues to enrich my life!!!

Charles Limb: Your brain on improv
This talk really excited me. I am a scientist and jazz singer and musician, and have often pondered to what extent jazz innovation truly reflects the 'creative spark'. I often find myself closing my eyes when I sing or solo on sax, perhaps to 'shut down' those parts of the cortex that 'interfere' (admittedly, harder to do that on a piano solo, but would have been awesome to test that as well). I understood from an interview with Dr. Limb that he only studied right-handed musicians, which is okay for a start, but would be great to see to what extent lefties' scans differ from the right handed. The reason I say this is that, as a left handed musician, I wonder what it would have been like to have learned to play piano 'backwards' as a child with the lower notes on the right. How would my bass accompaniments be different? How would my solos be different if I were using my dominant hand? The reason I say this is because you can hear the left-handedness of Bill Evans.
